    (57) A cap (2) installed in an ink jet recording head (IJU) for sealing an ink ejection orifice (113i) of the ink jet recording head (IJU) comprises a contacting member (20) and a pressing structure (2, 21B, 21F, 16a, 16b). The contacting member (20) is a member having an elastically deformable convex part (20A) which contacts a face (113e) on which the orifice (113i) is disposed and seals the orifice (113i). The pressing structure (2, 21B, 21F, 16a, 16b) presses the convex part (20A) of the contacting member (20) toward the face (113e) in responsive to installing the cap (2).
